Pentakis-trifluormethyl-benzoesaeure-ethylester, also known as ethyl pentakis(trifluoromethyl)benzoate, is a complex organic compound with the chemical formula C17H9F15O2. It is derived from benzoic acid, where all five hydrogen atoms on the benzene ring are replaced by trifluoromethyl groups (CF3), and an ethyl ester group (C2H5O) is attached to the carboxylic acid group. Pentakis-trifluormethyl-benzoesaeure-ethylester is characterized by its high symmetry and strong electron-withdrawing properties due to the presence of multiple trifluoromethyl groups. It is typically synthesized for use in advanced materials and pharmaceuticals, where its unique electronic and steric properties can influence the reactivity and stability of molecules.
The CAS Registry Mumber 862-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 2 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 862-54: (5*8)+(4*6)+(3*2)+(2*5)+(1*4)=84 84 % 10 = 4 So 862-54-4 is a valid CAS Registry Number.
